Ibook can't see full network

Ok, I have an ibook that connects to an 802.11 g d-link router that my PC is connected to as well. That router is connected to yet another d-link router with 3 PC's and a printer connected to it. The problem is that I can only see the 802.11g network (My PC), However when i disconnect my router and hook into the other one i can see all the other computers and the printer. Why cant i see the router with three pcs connected to it through my own router?

It doesn't work that way, you can't just change the subnet mask. I got my CCNA certification when I was 17, I don't remember too much of it now that I'm 20 but I know you can't just freely change the subnet mask without changing the IP. If both devices on your network are "routers" then you don't need both. Get rid of the one that doesn't have wireless and use the wireless one (assuming it has multiple ethernet ports on it, if not buy a switch) for all your computers and you should be fine.

I've tried and it for some reason when my second router dosnt have the first one in front of it none of the computers connected to it can get on the internet.
